Leviticus 20:20–21

If a man lies with his uncle’s wife, he has uncovered his uncle’s nakedness; they shall bear their sin; they shall die childless. If a man takes his brother’s wife, it is impurity. He has uncovered his brother’s nakedness; they shall be childless.

“ ‘If a man has sexual relations with his aunt, he has dishonored his uncle. They will be held responsible; they will die childless.

“ ‘If a man marries his brother’s wife, it is an act of impurity; he has dishonored his brother. They will be childless.

If a man sleeps with his aunt, he has violated the intimacy that belongs to his uncle; they will bear their guilt and die childless. If a man marries his brother’s wife, it is impurity. He has violated the intimacy that belongs to his brother; they will be childless.

“If a man has sex with his uncle’s wife, he has violated his uncle. Both the man and woman will be punished for their sin, and they will die childless.

“If a man marries his brother’s wife, it is an act of impurity. He has violated his brother, and the guilty couple will remain childless.

As for a man who lies with his aunt, he has exposed his uncle’s nakedness—they shall bear their sin; they shall die childless. As for a man who marries his brother’s wife, it is an abomination; he has exposed his brother’s nakedness—they shall be childless.

And if a man shall lie with his uncle’s wife, he hath uncovered his uncle’s nakedness: they shall bear their sin; they shall die childless. And if a man shall take his brother’s wife, it is an unclean thing: he hath uncovered his brother’s nakedness; they shall be childless.
